What I see in those videos looks just like my university, a bunch of people on what we call beach cruisers going a very short distance. Their speed indicates they aren't going far and aren't in much of a rush. Are people in the Netherlands strict about arrival times? Do they usually move at a slower pace?
In my city commuters go fast. We're going a few miles on a commute at least.
They're going quite a few miles on bike alone. 30-60 min commutes are not uncommon. Kids, Adults, Seniors. Hot or cold, rain or shine.
The time culture is similar to Germany: you have to be punctual. This means you need to leave on time in order to arrive on time. As a general rule in real-world traffic: Speeding might not actually help you arrive all that much quicker, you just feel like you do. An objective instrument (such as a GPS) may well inform you otherwise.
Also, on a bike: if you're traveling longer distances, you need to pace yourself, lest you run out of steam half-way.
The infrastructure is good though, in municipal zones the cycle distance (and time!) can often be shorter than the car-distance; because bikes can take more short-cuts and are easier to park. And for longer distances it's possible to eg. park your bike at a station and continue by bus or train.
